摘要
浮动核电站受海面风浪影响会产生多种运动形式,造成堆芯热工水力特性改变,威胁反应堆运行安全。针对我国浮动核电站的研发设计需求,对海洋条件下反应堆热工水力特性的国内外研究进展进行综述,重点关注了海洋条件下流动换热、汽泡行为、流动不稳定性与临界热流密度等方面的研究进展,并提出了未来研究中需重点关注的内容。
The use of floating nuclear power plants( FNPPs) is an effective way to solve the energy supply problems for marine resource development and island construction. Because of the effects of ocean waves and self-movement,operating FNPPs using the ship-based platform can generate many types of movement,such as heaving and rolling,which can change the thermal-hydraulic characteristics and threaten the nuclear reactor safety. This paper reviews the research progress of nuclear reactor thermal-hydraulic characteristics under ocean conditions in the past decades,and focuses on the thermal-hydraulic problems under ocean conditions,including heat flow and transfer,bubble behavior and flow pattern conversion,flow instability,and critical heat flux( CHF). Finally,the paper discusses and presents the key points that require attention in future research;thus,it can serve as a reference for the design and development of FNPP in China.
